Solve the system r + s = -12

2 answers:

6 0

r + s = -12 so r = -s - 12
4r - 6s = 12

substitute r = -s - 12 into 4r - 6s = 12

4r - 6s = 12
4(-s - 12) - 6s = 12
-4s - 48 -6s = 12
-10s = 60
s = -6

r = -(-6) - 12
r = 6 - 12
r = -6

Answer:

B. (-6,-6)

Step-by-step explanation:

r + s = -12 so r = -s - 12

4r - 6s = 12

substitute r = -s - 12 into 4r - 6s = 12

4r - 6s = 12

4(-s - 12) - 6s = 12

-4s - 48 -6s = 12

-10s = 60

s = -6

r = -(-6) - 12

r = 6 - 12

r = -6

So therefore the answer is (-6,-6).

How to solve (8x-30)+(6x+10)=180

lozanna [386]

Add the like terms. So I'll add the variables. 8x+6x is 14x. Now add whole numbers. 30+10 is 40. Our new expression we'll be 14x+40=180. Subtract 40 from 180. 180-40=140. Now we have the expression 14x=140. 140 divided by 14 is 10. So x is 10.
